This invention relates to certain improvements in sliding doors and has relation more particularly to a device of this general character especially designed and adapted for use on freight cars and it is an object of the invention to provide novel and improved door of this general charactercomprising two sections, said sections having slidingmovement one independentl of the other into either open or closed pot don.

Another object of the invention is to provide a novel and improved device of this general character comprising an upper and lower section each. having sliding movement one independent of the other and wherein the doorway is intersected by a beam provided with means to afford a guide for each of the sections of the dooiy said beam be ing movable, when desired, to the upper portion of the door opening whereby provision is made to permit articles of a relatively large size to be placed. within the car body when the occasions of practice mayrequire.

Furthermore, it is an object of the inven tion to provide a novel and improved door comprising separable sections each having independent movement together with guide and supporting means for each of said sections, said means being slidably positioned betweenthe jambs of the door opening and movable when required into an inoperative position together with means for locking said member in operative position The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved sliding door whereby certain i1nportant advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

in order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompa ying drmvings wherein:

Fr l is an elevational view illusti a car door constructed in accordance with an embodiment of my invention, one of the door sections being in open position,

igure 2 is an enlarged m ntary view partly in section and partly in top plan,

illustrating in detail the holding means at one end portion. of the beam Figure 3 is a view partly in section and partly in elevation of the structure shown and illustrated in Figure 2 and Figure 4 is a sectional view taken substantially on the line iel of'Figure 3.

As disclosed in the accompanying dram ings, D denotes a door opening' of a tional type employed in connection with freight cars or the like and with which s associated my improved door. My improved door comprises two sections 1 and of metal or other solid material, each of said sections being adapted to have sliding; movement lengthwise oi the car so that the same can be adjusted into either closd or open position with respect to the opening D. The lower door section 1 has bottom edge riding'upon the guide rollers Z suitably secured to the adjacent side wall l the car while the upper marginal por tion of said lower door section 1. has sliding engagement WltlllIl a track v l secured to the adjacent side wall li and to 7 one side oi the door opening l). The upper door section 2 1S slidably engaged within.

the traclrways 5 also secured to. theadjacent side wall of the car to one side or? the door. opening l). The upper trackway 5 en tends over the upper portion of the open ing D so that the upper section 2 may have the desired or requisite sliding movement.

B. denotes horizontally disposed beam positioned between the jambs 6 of the door openingl), the oppositeend portions of said beam B extending between the vertically disposed plates 7 secured to the opposite sides of the upper portions of the jambs 6 and extending to substantially the tops thereof.

Secured to the outer face of the beam B are the trackways 4L and 5 which when the beam B is in its lowermost position, aline, respectively, with the trackway l and the lower trackway 5 so that with the beam in its lowered position the door sections 1 and 2 may have sliding movement into closed position with respect to the opening D.

lin loading or unloading; the car either of the door sections 1 or u may he slid. into open position as the occasions ot practice may prefer. In the event the load consists of grain, coal or other material capable of flow, I provide the lower portion of the door section 1 oh a supplemental door opening-9 which, when the section 1 ishi closed position, is closely positioned to the bottom of the car. 9/ isa door 10 herein d closed as having up ward swinging movement when moved into open position. Associated ith the door 10 and the portion of section l'dei'ining the lower portion of the door opening 9 are coacting locking members 11 which may be of any type preferred.

The downward in vement theibeam l? is limited by the stops 12 suitably secured to the jambs 6 and with which the under face of the beam B at the extremities thereof: contacts.

When the beam B is at the limit of its downward movement the same is held. against upward mover rent by the sliding bolt 1/1- mounted'upon the opposite end. portions of the beam B and each of said bolts being engageable with a suitable keeper '15 in the adjacent jamb 6.

Extending outwardly from the inner face of the beam B adjacent the opposite ends thereof are the eye members 16, each of which is adapted to be engaged, when the beam 13 is at the limit of its upward movement, by hook members 17 supported by and depending from the top piece or crown 18 of the frame of the door opening D. i

It is to be understood that before the beam B is raised upwardly the door sections 1 and 2 are first moved into open position or in a 7 position to one side of the door opening,

When the door sections 1 and 2 are in closed position the same are held closed by the co-acting locking members 19.

From the toregoing description it is Associated with the door opening thought to be obvious that sliding door constructed in accordance with my invention is parinlarly well adapted for use by reason of convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and sp 't thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed. l

1 claim:

In combination with wall provided with a door openin supporting; means positioned above and below the opening and extending to one side thereof, supporting means positioned to one side or" the door opening at a point between the ends or" the opening, sliding door sections en aged with said supporting means each of said sections being slidable to overlie a portion of the opening or to position at one side thereof, plates secured to the opposite sides of the wall at the upper portion ofeach side 01"- the opening and extending within the opening to provide guideways, a beam positioned within the opening and extending therea-cross, the eX- tremities of the beam engaging between the plates, said beam being movable toward an end of the opening, said beam having supporting means registering with. the second named supporting means when the beam is at the limit of its downward movement in one direction within the opening, strips disposed transversely of the guideways with which the extremities of the beam contact TONY RUBIN.
